dasdseq

NAME

SYNOPSIS

DESCRIPTION

Hercules command to retrieve a DSORG=PS (sequential) dataset from CKD/CCKD DASD. The dataset is presumed to be encoded in EBCDIC. The second form of the command is for ’expert mode’ users, and allows more advanced access to data on the DASD image.

OPTIONS

The following options are used to specify dasdseq behavior. Surround each option by blank(s). Options are divided into three categories: required, optional, and expert mode operands.

When -abs is specified, each -abs group specifies one dataset extent. For multi-extent datasets, -abs groups may be repeated as needed, in the order in which the dataset’s extents occur. A maximum of 123 extents are supported. With -abs, no VTOC structure is implied; a F1 DSCB will not be sought. Dasdseq will frequently report ’track not found in extent table’ (along with a message from fbcopy about rc -1 from convert_tt) due to potentially missing EOF markers in the extent, and the fact that the F1 DSCB DS1LSTAR field is not valid. Check your output file before you panic. Fbcopy -abs ignores EOF, in case you are attempting to recovery PDS member(s) from a damaged dasd volume, preferring to wait until all tracks in the extent have been processed. Tracks containing PDS members may have more than one EOF per track. Expect a lot of associated manual effort with -abs.

When -abs is -not- specified, filename specifies the MVS DSORG=PS dataset on the volume. The dasd image volume containing the dataset must have a valid VTOC structure, and a F1 DSCB describing the dataset.

filename
will be the filename of the output file in the current directory; output filename in the same case as the command line filename.
